More than 30 people across four US states have been poisoned by bacterial endotoxins after receiving intravenous drips containing glutathione at wellness clinics, according to health authorities. The issue highlights the dangers of unregulated supplement practices in medical settings, particularly the use of glutathione marketed without scientific evidence for "detoxification" and other health claims, despite lacking FDA-approved status.

The problem stems from compounding pharmacies using dietary supplement-grade glutathione powder—intended for oral consumption—instead of pharmaceutical-grade purified products suitable for injection. The contaminated glutathione came from Medisca Inc. in New York and contained elevated bacterial endotoxins. Three Texas pharmacies have recalled their products, including those branded as Myer's Cocktail and Tri-Immune Boost. Victims across Texas, Washington, Florida, and New York have experienced symptoms ranging from fever and severe headaches to shock-like conditions; at least three people have been hospitalised, with one requiring intensive care. The FDA previously issued a similar warning in 2019 about the same type of contamination.
